Buck-Boost acts as Buck converter for duty cycle is equal to_________(

1.	Buck-Boost acts as Buck converter for duty cycle is equal to_________(a) .9(b) .7(c) .6(d) .4I have been asked this question by my school teacher while I was bunking the class.The query is from Solid-State Switching Circuits topic in division Introduction to Solid-State Switching Circuits of Electric Drives
Answer» CORRECT choice is (d) .4 The best explanation: The OUTPUT voltage of the buck-boost converter is Vo = D×Vin ÷ (1-D). It can step up and step down the voltage depending UPON the value of the duty cycle. If the value of the duty cycle is LESS than .5 it will work as a buck converter. The ANSWER is .4.
